Ad hoc crisis response and international organisations (ADHOCISM) is a project funded by the Research Council of Norway (RCN).

More on the team and the project can be found here.

In this page, we present some of the results of the dataset we have been developing in the project, with a focus on the membership of states in Ad Hoc Coalitions (AHCs). The ADHOCISM dataset provides a valuable resource for understanding the characteristics and dynamics of AHCs and seeks to foster a better integration of AHCs in the study of conflict management and global governance at large. We have a dataset covering 627 AHC-year observations, with 84 different AHC cases, coded along 38 variables in different dimensions: membership, duration, organizational structure, geographical orientation and mandate. More on the selection of cases can be found here.

Member states in Ad Hoc Coalitions (AHCs)

In this page, we are presenting the membership networks of states in coalitions throughout the years. In the initial graph, we display the complete network of countries, including both coalition members and target countries, for the year 1975. To enhance clarity, we weighted the centrality of each country based solely on its out-degree. As a result, in this example, Poland, Canada and India emerge as the most central nodes. In this specific year, Poland participated in three coalitions: ICCS - South Vietnam, ICSC II - Laos and the NNSC.

Nevertheless, the presence of target countries in the network introduces bias. Therefore, we intentionally remove the target countries from the graphs. The exclusion of these target countries is necessary as they tend to exhibit high centrality in the dataset, primarily due to their reception of numerous edges, changing the measures.

For the year 1975, we present the following graph; however, it still includes the coalition IDs. The issues of bias persist since coalitions and member states are distinct entities.

To address this concern, we display a bipartite network that reflects the co-membership of states. This new network will distinctly represent the relationships between member states in a same coalition. In this case, the edges in this network are undirected, meaning that member states do not have a specific direction of contribution. The width of the edges is weighted according the number of coalitions in which the countries have co-membership.

Presented below is a map presenting the connections between coalition members and their target countries by year. This visual representation provides a overview of the relationships, aiding in the understanding of international crisis responsses and their evolving nature.
